SOLUTION: I am having trouble factoring the following quadratic equation. I have tried grouping and pulling out a common term but I just can't get it. Any help would be appreciated.
{{{x^
You can see that the 1st 3 terms are in the form of a^2 - 2ab + b^2, which is
(a - b)^2
So it can be first written as
Now this is of the form a^2 - b^2, which is (a+b)*(a-b)
=
=
which is the final factorization.
Hope you got it :)
